Ageing reveals the latent effects of early life stress on respiratory and metabolic function in female rats: Novel insights into the sex‐specific origins of sleep apnoea

Experimental Physiology, Volume 111, Issue 3, Page 1466-1482, 1 March 2026.
Abstract Sleep apnoea (SA) is ∼2 times more prevalent in men than women. However, this changes at menopause as the occurrence of SA increases and matches that of men. Menopause is a natural process, but it remains unclear why SA emerges only in a subpopulation of ageing women.

Joint US/USSR study: Comparison of effects of horizontal and head-down bed rest [PDF]

An account is given of the results of the first joint U.S./U.S.S.R. bed rest study. The study was accomplished in two parts: A soviet part (May to June 1979) and an American part (July to August 1979).

Human adaptation to high‐altitude: A contemporary comparison of the oxygen cascade in Andean, Tibetan and Ethiopian highlanders

Experimental Physiology, Volume 111, Issue 3, Page 849-865, 1 March 2026.
Abstract Human populations native to high altitude have evolved distinct physiological adaptations to chronic hypoxia. This adaptation is evident in the O2 transport cascade. In this review, with brief inclusion of the related genetic adaptations, we compare the O2 cascade across three well‐characterized high‐altitude populations: Andeans (Aymara and ...

Ageing attenuates regional vasoconstriction during acute lowering of upper and lower limbs

Experimental Physiology, Volume 111, Issue 3, Page 674-683, 1 March 2026.
Abstract The venoarteriolar and myogenic response (VMR) is a non‐adrenergic, non‐baroreflex‐mediated mechanism that increases local vascular resistance and contributes to blood pressure (BP) regulation during orthostasis. Despite the importance of the VMR in human cardiovascular control, no information exists elucidating possible differences in the VMR

A Wearable Technology Revisited for Cardio-Respiratory Functional Exploration: Stroke Volume Estimation From Respiratory Inductive Plethysmography

, 2013
International audienceThe objective of the present study is to extract new information from complex signals generated by Respiratory Inductive Plethysmography (RIP). This indirect cardio-respiratory (CR) measure is a well-known wearable solution.

Ouabain‐induced hypertension in rats: Mechanisms, variability and translational implications

Experimental Physiology, Volume 111, Issue 3, Page 653-673, 1 March 2026.
Abstract Ouabain‐induced hypertension is a multifactorial and condition‐dependent phenomenon involving coordinated actions across vascular, renal and central nervous system pathways. At the vascular level, ouabain inhibits Na⁺/K⁺‐ATPase, particularly the α2‐isoform, leading to elevated intracellular Ca2⁺, enhanced vasoconstriction and structural ...

Technical aspects of impedance plethysmography.

Journal of postgraduate medicine, 1991
This paper describes the basic methods for measurement of body impedance, electrodes and their configuration, and the measuring instrument with its limitations. A microcomputer assisted impedance plethysmograph system, developed at BARC and different lead configurations for impedance plethysmographic investigation are also described.

Oral amino acid tracer delivery detects feeding and exercise changes in myofibrillar protein synthesis rates in male adults

Physiological Reports, Volume 14, Issue 5, March 2026.
Male participants were randomly assigned to consume [13C]leucine and [D5]phenylalanine tracers alone (FAST) or with a complete mixture of amino acids (0.25 g/kg) and carbohydrate (0.75 g/kg) at rest (FED) or after a bout of resistance exercise (EXFED). Plasma enrichment of both tracers increased rapidly after ingestion and remained elevated for up to 4–
